Abstract: Description according to the present disclosure relates to an apparatus for inspecting a welding tip of a spot welding gun, and more particularly, to an apparatus for inspecting a welding tip of a spot welding gun, the apparatus enabling a user to replace a camera module swiftly and conveniently.

Abstract: The present invention discloses methods and apparatus for increasing inspection efficiency and reducing time for analyzing an image when inspecting contamination and alignment of the welding tip of the spot welding gun. An apparatus for inspecting a welding tip according to some embodiments of the present invention is configured to inspect the contamination and the alignment of the welding tip based on an end-surface image and a profile image of the welding tip. In particular, when recording the welding tip through an internal housing arranged in an internal space of an external housing, the noise generated from an external light source can be blocked, and hence the contamination and the alignment of the welding tip can be inspected by using a clearer image, thus improving the accuracy of the inspection.
